If you plot the points you can easily find the answer. (X,Y) The x-axis is the horizontal line and the y-axis is the vertical line.
When fireworks display made of copper is burned, it lets out light with wavelengths, v v, that satisfy the relationship | v − 45
5 | < 23 |v-455|<23. Write this inequality without absolute values, find the range of possible values for v v, and then using the preceding list of wavelengths, determine the color of that copper fireworks display.
